Dolphins promote DT Isaako Aaitui to the 53-man roster

The Miami Dolphins have promoted defensive tackle Isaako Aaitui to the 53-man roster heading into Sunday's 1 p.m. home game against the Buffalo Bills.

Aaitui initially impressed the Dolphins coaching staff during training camp in 2012, but he was one of the final players released and got claimed by the New York Jets.

During his first week with the Jets Aaitui tore his ACL and was placed on injured reserve. He spent the past year rehabbing the knee. He spent training camp with the New Orleans Saints but didn't make it onto the 53-man roster.

The Dolphins added Aaitui to the Dolphins' practice squad during the third week of the season and he's impressed Miami's coaches since joining the team.

The Dolphins had an opening on the 53-man roster because defensive tackle Marvin Austin was released earlier this week.

Aaitui will likely be used on special teams, and as part of the defensive tackle rotation, which features Paul Soliai, Randy Starks and Jared Odrick, who also plays defensive end.
